Cov kws tshawb fawb ntawmDelft University of Technologyhauv Netherlands tau tsim txoj kev sib tiv toj (IBC),tooj liab-indium-gallium-selenide (CIGS) hnub ci cellnrog rau sub-micron tuab ntawm 673 nm.
Cov kws tshawb fawb Delft tau hais tias muaj kev sib txuam, pem hauv ntej / rov qab back sib cuag (FBC) lub hnub ci hlwb raug teeb meem tsis pom kev zoo vim muaj kev cuam tshuam los ntawm parasitic nqus los ntawm lawv cov khaubncaws sab saum toj uas tuaj yeem ua kom 10% poob rau hauv photocurrent ntom. Tsis tas li ntawd, cov kws tshawb fawb tau hais tias, "Tus CIGS lub hnub ci hloov pauv tau, lub plhaw hlau ua rau lub ntsej muag txuas ntxiv, txo qhov kev ua haujlwm zoo dua ntxiv."
Lub xov tooj ntawm IBC tsim los ntawm pab pawg Delft tau muab piv nrog 11.Solliance Kev Tshawb Fawb Hnub Ci, nrog pab pawg Delft tsom tshwj xeeb rau kev ua yeeb yam nqus cov yeeb yam.
Lub Delft cell tshwj xeeb ua ob-txheej txheej los tiv thaiv kev xim raws li cov khoom siv txhuas oxide (Al2O3) thiab magnesium fluoride (MgF2)). “Cov qib siab zoo ntawm Al2O3thiab MgF2rau qhov haujlwm no yog 80 thiab 85 nm, raws, "hais ntawm Delft pab pawg. “Tus Al2O3txheej nyob rau sab pem hauv ntej ntawm lub nqus tau pabcuam ua rau [txheej] tshuaj lom neeg thiab hluav taws xob passivation. "
Thaws Khoom
Cov kws tshawb nrhiav tau tso ib qho kev cuam tshuam rau sab nraub qaum ntawm lawv lub cuab yeej los tsa qhov tshwm sim ntawm kev nqus ntawm cov duab hluav taws xob thib ob.
Gium gallium ‐ doped zinc ‐ oxide (GZO) tau siv los ua n ‐ doped pob tshab ua rau muaj oxide ntawm IBC ntawm tes. Cov compound ntawd tau hais kom muaj lub siab doping concentration, qis nqus coefficient, siab thermal stability thiab tsis pub dawb-cab kuj.
Nrog rau kev sim ua nruab nrab ntawm ob lub hnub ci hlwb ua los ntawm kev ntsuas cov ntsuas sib txawv ntawm cov ntsuas thiab cov khoom siv nqus cov yam ntxwv, Delft cov cuab yeej ua kom pom cov khoom siv 17% ua tau zoo. "Txij li qhov ua tau zoo ntawm peb qhov kev suav tawm ntawm qhov ntsuas qhov tsis pom qhov tsis zoo, qhov qis ntawm qhov pom ntawm qhov pom qis, qis dua li lub xeev" kev kos duab CIGS absorber cov khoom, peb tau kawm txog qhov tshwm sim ntawm lub cev tsis xws luag ntawm lub cell, "cov kws tshawb nrhiav teev tseg. "Peb tau pom tias los ntawm kev txo cov kev tsis txaus siab feem ntau los ntawm 5 × 1013cm−3mus rau 1 × 1013cm−3, qhov ua tau zoo tuaj yeem hloov kho mus rau 19. 7%. "
Cov kws tshawb nrhiav tau hais tias muaj qhov tsis zoo them nqi hauv Al2O3txheej kom ntseeg tau qhov kev siv hluav taws xob thiab ua kom muaj qhov sib txawv ntawm qhov sib txawv me me-dav qhov tseem ceeb. "Peb tau qhia yuav ua li cas IBC cov qauv nrog kev pom zoo ntawm cov chaw sib tw thiab qhov nqus tau zoo tuaj yeem pab peb ua tiav qhov kev ua tau zoo nrog sub-micron CIGS txheej," hais tias Delft pab pawg.
Kev Ua Lag Luam
Thaum lees txais cov txheej txheem ua piv txwv uas kim yuav tsum tau rov ua lub cuab yeej tuaj yeem ua pov thawj txoj hauv kev ua lag luam ntawm lawv cov thev naus laus zis, pab pawg Delft tau hais tias lawv tus qauv tsim tshwj xeeb rau peb thiab plaub ‐ qhov xaus tandem hnub ci khoom siv.
Lub Delft lub hnub ci xov tooj yog tau piav qhia hauvKev sib xyaw ua ke rov qab ‐ cov qauv sib cuag: Ib txoj hauv kev sib txawv ntawm cov ua haujlwm siab rau ultrathin tooj liab indium gallium (di) selenide hnub ci hlwb, luam tawm nyob rau hauvProgess hauv Photovoltaics.
Cov kws tshawb fawb los ntawm Helmholtz-Zentrum Berlin (HZB) thaum Lub Plaub Hlis tau tshaj tawm tias lawv tau ua tiav24.16%efficiency nrog atandem cell uas sib xyaw CIGS thiab perovskite thev naus laus zisCov. Ntais ntawv coj mustandem ntaus ntawvefficiency dhau ntawm23. 35% ntawv rau ib tug kheej 1 cm² CIGS ntawm tesuas tau teeb tsa los ntawm Hnub Ci Frontier hauv Lub Ib Hlis xyoo dhau los.
